ST. LOUIS (AP) — Kolten Wong hit a grand slam that backed Lance Lynn and led the St. Louis Cardinals over the Cincinnati Reds 4-1 Monday night. Wong connected on a 3-2 fastball from rookie Raisel Iglesias (1-3) with two outs in the fourth, putting St. Louis ahead 4-1. Wong’s second career grand slam easily cleared the right- field wall, landing in the home bullpen. The Cardinals have won six of seven, are a big league-best 64-35 record and lead the NL Central by 6 ½ games.

Lynn (8-5) allowed one run and five hits in seven innings, improving to 7-3 against the Reds. He has won five of his last six decisions overall. Trevor Rosenthal earned his 31st save in 33 chances after getting two days off.

Catcher Yadier Molina was replaced by a pinch hitter in the bottom of the fifth inning of a game against Cincinnati because he was feeling ill. Tony Cruz grounded out to end the fifth and then took over behind the plate against the Reds on Monday night. Molina doubled and scored on Kolten Wong’s grand slam in the fourth.

St. Louis Cardinals players arrived to un-air conditioned Busch Stadium on Monday. The problem was fixed by mid-afternoon, several hours before a game against the Cincinnati Reds. Manager Mike Matheny downplayed the situation, noting he grew up without air conditioning. Matheny joked that his wife sets the thermostat at “about 47 degrees” and that he thought they were “trying to raise penguins.” The problem was first noted during a news conference at adjacent Ballpark Village to promote the United States’ opening qualifier for the 2018 World Cup, in November.
