On Tuesday, for the second time inside of a week, two of the NL’s top starting pitchers in terms of ERA — the Cubs’ Jon Lester (2.10, third in the league) and the Dodgers’ Ross Stripling (1.99, which would rank second if he weren’t 4.2 innings short of qualifying) — will square off, this time in Los Angeles. On June 20, Lester got the upper hand, throwing seven shutout innings in a 4-0 win, the latest strong outing for the 34-year-old southpaw, who’s been on quite a roll lately.
Indeed, Lester has surrendered a mere two runs and 13 hits in his last four starts (27 innings), both via solo homers by Cardinals in a June 15 game that the Cubs won, 13-5. Only once in his past 10 starts has he allowed more than two runs (four in six innings versus the Pirates in a May 29 win), good for a 1.58 ERA over 62.2 innings. Depending upon the schedules of Max Scherzer (10-3, 2.09 ERA) and Jacob deGrom (5-3, 1.69 ERA) as well as the preferences of their respective teams, it’s not completely farfetched that NL All-Star manager Dave Roberts could give Lester (who’s a gaudy 9-2 to go with that ERA) the start on July 17 at Nationals Park, though you can imagine the pressure will be on the Nationals to make Scherzer available, health permitting.
Despite those superficially glossy stats, Lester is nowhere near the top of the NL pitching WAR leaderboard. His 0.9 WAR ranks just 26th in the NL, somehow behind the WARs of the likes of the Marlins’ Jose Urena (2-9, 4.40 ERA, 1.4 WAR), the Phillies’ Vince Velasquez (5-8, 4.69 ERA, 1.4 WAR), and the Mets’ Zack Wheeler (2-6, 4.85 ERA, 1.2 WAR), none of whom are likely to make the NL All-Star team, let alone get consideration for the start.
The disconnect for Lester is that his FIP (4.19) is almost exactly double his ERA, ranking 28th among the 43 pitchers with enough innings to qualify and 37th out of 59 with at least 60 innings; his 104 FIP- tells us that he’s actually 4% worse than league average on that front. The 2.09 runs per nine differential between his ERA and FIP isn’t just the majors’ largest this season, it’s the largest from an ERA qualifier since 1901. Even if you drop the innings threshold to 90 (Lester’s total), he’s just a whisker away from the lead:
