ST. LOUIS — It was over 90 degrees when Andrew Painter left the dugout for the first time Monday, walking to left field alongside the Philadelphia Phillies pitching coaches to run through his prestart routine. By the time he departed the mound after 5 1/3 no-hit innings spoiled by back-to-back hits at the very end, the temperatures had somewhat cooled, but sweat clung to everyone on the field like a garment.“Went to the rosin, like, a lot,” Painter said. “Just trying to get a grip on the ball and make pitches.”Maybe this was a typical August evening in St. Louis, the air thick and players boiling as they worked, but all that transpired in the Phillies’ 6-5 win against the St. Louis Cardinals was atypical: a plan to get eight innings out of Painter and long man Alan Rangel come hell or high water, and an unusual starting lineup.Monday’s game was all too important for the Phillies to ignore. Barely 24 hours before the club took the field for defense at Busch Stadium, it had capped off a 12-inning win in Philadelphia with a gassed bullpen and an exhausted offense. It needed something, anything from its pitchers. This was a game the Phillies simply needed to get through without an implosion.Dave Dombrowski on Phillies' position shifts for Arraez tradeJayson Stark“It was one of the easiest games I’ve ever managed, actually,” interim manager Don Mattingly said. “Because you know you’re not doing anything.”Those no-hit innings from a pitcher who was in Triple A two weeks ago, followed by 2 2/3 innings from a pitcher who was in Triple A two days ago, followed by a reliever’s first career save was arguably more than Mattingly could have hoped for — even if things turned sideways at points.
