At a most opportune time, Phil Hughes appears to be rounding into his best form of the season.
The Yankee starter shut out Boston for 7 1/3 innings, helping New York grind its way to a 2-0 win in the series finale.
The win kept the Yanks and Orioles tied for first in the AL East, as Baltimore completed their three-game sweep of the Rays with a 3-2 win in 14 innings.
That puts the Rays in a troubling predicament, because they'll have to catch either the O's or Yankees for one of the two wild card spots as the A's are a game up on both Baltimore and New York, but Tampa Bay is four back of them.
There were just two NL games on Thursday, but the results impacted the wild card race.
Allen Craig went 2-for-5 and drove in the winning run in the top of the seventh with a single after doubling in an earlier at-bat.
Lance Lynn (15-7) allowed the only Dodger run, going six innings for the Cards before giving way to a trio of relievers, ending with Jason Motte picking up his 34th save.
The results left St. Louis five behind Atlanta and in position for the second wild card spot. The Dodgers trail the Cardinals by two games. The Pirates are three back, followed by Milwaukee, 3 1/2 behind, Philly, 4 out, and Arizona, 4 1/2 behind.
