National League Contender Concerns
While the American League playoff field appears to be set, the National League should provide a fascinating September with eight teams vying for five spots and no division lead currently greater than three games. Here is a look at the eight contenders and a possible concern down the stretch or in the playoffs in a wide open NL pennant race.
Chicago Cubs (81-57): Too Many Lefties?
The 2016 World Series champions have the best record in the NL and are near certain to be in the playoffs in some fashion, though the division lead over Milwaukee has slipped to just three games. The Cubs have perhaps the most established starting rotation of all the contenders with five viable options on the mound. Four of those starters are left-handed however and looking at the current playoff field, many of those teams have feasted on left-handers this season.
The Cubs would likely be comfortable throwing Jon Lester, Cole Hamels, Kyle Hendricks, or even Jose Quintana in a big playoff game but only Hendricks is right-handed. Potential foes Colorado, Arizona, St. Louis, and Atlanta all have team OPS marks of at least 40 points higher vs. left-handers than vs. right-handers as the Dodgers and Phillies would be the only NL foes that are at a significant disadvantage vs. the left-handed heavy rotation for the Cubs. Chicago is a deserving NL favorite but they may draw a problematic matchup along the way.
Milwaukee Brewers (79-61): Who will Pitch?
Milwaukee is chasing down the Cubs in the NL Central race despite only two starters having enough innings for the Brewers as qualified starters on the season, Jhuolys Chacin and Chase Anderson. Both have suspicious numbers with Chacin 14-5 despite a 4.45 xFIP and in eight of his 29 starts he has allowed four or more runs including allowing eight or more runs twice. Chacin and to a more significant degree Anderson both have worse numbers at Miller Park. Anderson owns a 2.89 ERA on the road but a 5.01 ERA at home and if Milwaukee ends up in one game wild card draw it will be an interesting decision on who to start.
Junior Guerra looked like the team’s best pitcher in May and June but he owns a 7.62 ERA in his last nine starts. Newcomer Gio Gonzalez hasn’t had a great season and he has zero wins in six career playoff starts and while Wade Miley has been on a roll of late there isn’t much in his career numbers to suggest it is a sustainable pace. Milwaukee’s opponent could also be one of the aforementioned NL teams that rakes against left-handed pitching as well. Milwaukee’s bullpen has seen its numbers deteriorate as the Brewers will likely face a taxing September looking to hold on to a spot.
St. Louis Cardinals (77-62): Unsustainable Hot Streak?
The Cardinals have put together an epic second half run to climb into the NL playoff picture going 23-9 since August started. With a 1-3 start to September and a decline in recent scoring there are signs that that hot streak is ending as St. Louis clings to the final wild card spot. 16 of the 22 August wins came against teams that wouldn’t make the playoffs right now as the schedule certainly helped the Cardinals climb back into the race.
Four of the final five series will be against playoff contenders although the Cardinals do have 13 of the final 19 games at home. St. Louis has had surprise pitching stars but Miles Mikolas, Jack Flaherty, and John Gant all appear to be great overachievers in viewing their ERA against their FIP and as teams have more film and more at-bats against them, the numbers could erode.
Colorado Rockies (76-62): Law of Averages?
All season long Colorado has outperformed it scoring numbers currently 14 games above .500 despite being -10 in scoring differential. Like Arizona, Colorado has a difficult remaining schedule with 13 games against the two division rivals they are fighting with in the NL West race plus drawing the Phillies and Nationals in the final two home series. A Rockies team that has been fortunate going 24-14 in one-runs games while just 11-14 vs. the Diamondbacks and Dodgers could have trouble holding on to the division lead.
Colorado only has a winning record vs. Atlanta among the seven other potential NL playoff teams and the Rockies have been outscored by nine runs despite going 18-14 since August started. Colorado has been outscored at home on the season and still has a negative scoring differential in going 25-17 since the All Star break. The Rockies do have a good defense and a capable bullpen while the unimposing starting staff led by Kyle Freeland has figured out how to pitch at Coor’s Field. Colorado would be a very improbable NL playoff threat historically with the current scoring numbers however.
Atlanta Braves (76-62): Unproven Ace?
The NL Cy Young race will be very interesting but more incredible is that the three likely leaders in that race might not be in the playoffs. Jacob deGrom and Max Scherzer are on losing teams and while Aaron Nola still has a realistic path to the playoffs the Phillies certainly have work to do to get him there. Add that long time NL Cy Young contenders like Clayton Kershaw, Madison Bumgarner, and Zack Greinke would all also miss the playoffs as of today’s standings and the NL playoff picture won’t have many proven starters that batters will fear in October.
Mike Foltynewicz won’t win the Cy Young but he could be among the top vote getters actually on a playoff team. A 1st round pick of the Astros in 2010 Foltynewicz will turn 27 as the playoffs begin and while he is just 10-9 his 2.80 ERA and 10.4 K/9 showcase his potential. His strikeout rate is significantly higher than in his past MLB seasons as is his walk rate and a more realistic 3.68 xFIP overshadows his ERA. Since mid-July his ERA is 3.54 with a decline in his strikeout numbers as it isn’t clear he is ready for the big stage in October as his best work was done in the season’s first three months.
Los Angeles Dodgers (76-63): Close Game Failures?
The Dodgers have the top scoring differential in the entire NL yet have been outside of the postseason picture much of the season. Los Angeles owns a marginal 39-35 record home and the 4.7 runs per game scoring average has been built on blowouts. The Dodgers have 25 wins and only eight losses by five or more runs and those 33 games have accounted for more than the +133 scoring differential for the team on the season. The Dodgers are .500 in one-runs games and .500 in extra-inning games and thus is only slightly above .500 since August despite big offensive production.
The bullpen is an easy target but with a 3.85 season ERA it has been a respectable unit and the Dodgers actually own the second best team ERA in all of baseball behind Houston. The Dodgers have blown 26 save opportunities this season for the third most in baseball and the Dodgers have gone 31-32 in games decided by the bullpen. That means the strong rotation simply hasn’t factored in enough decisions as only the Rays (who employ the opener frequently) have had more outcomes determined by relievers. The Dodgers are running out of time for their record to catch up to their production.
Arizona Diamondbacks (75-64): Brutal September Schedule?
Arizona has recently surrendered the NL West lead they have held for much of the season but the Diamondbacks still look like a serious threat. With Zack Greinke, Patrick Corbin, and Zack Godley plus Robbie Ray and Clay Buchholz the starting options for Arizona are formidable while the Diamondbacks have had the NL’s best bullpen numbers this season.
Arizona has likely the toughest remaining path to the playoffs however as only one series remains vs. a team that isn’t in a playoff race. Seven remaining division games with Colorado loom large but the Diamondbacks also have the Braves, Cubs, and Dodgers for a combined 10 games while still having an interleague road series with the Astros as well. The final three games in San Diego provide a favorable finish but that also means if Arizona is on the road for a potential wild card game they could face a long trip on a short turnaround.
Philadelphia Phillies (73-65): No Offense?
Philadelphia is by far the worst scoring team of the playoff contenders actually only outscoring the Mets, Giants, Padres, and Marlins on the season among NL teams. Philadelphia has averaged just 4.2 runs per game while going 20-23 since the All Star break, getting outscored by 24 runs in that span. The numbers are going in the wrong direction as well as Philadelphia has scored fewer than 3.8 runs per game since August started.
Philadelphia has a high-ceiling rotation but in the last four weeks over 24 games Philadelphia has hit .244 as a team with a .711 team OPS. In that span Philadelphia has struck out almost four times as often as it has taken a walk. Philadelphia has really poor recent numbers vs. left-handed pitching while also featuring a 30-39 road record that is by far the worst of the NL playoff threats. That does mean that Philadelphia is an impressive 43-26 at home but the current picture allows for a very slight chance that Philadelphia will get many opportunities at home early in the playoffs.
