ST. LOUIS (AP) — If the St. Louis Cardinals are going to make the playoffs, rookie starter Luke Weaver will be a big reason why.
Weaver pitched shutout ball into the sixth inning and also drove in a run Friday night, helping the Cardinals improve their postseason hopes with a 4-1 win over the Pittsburgh Pirates.
“It’s just real fun to watch him take advantage of an opportunity like this this time of season,” Cardinals manager Mike Matheny said.
The Cardinals have won seven of nine, pulling within four games of the NL Central-leading Cubs. St. Louis is even closer in the chase for the second wild-card spot.
The Pirates have lost three in a row.
Weaver (5-1) has won five straight decisions and his last four starts, not allowing more than two runs in any of them. He gave up seven hits, walked none and struck out seven in 5 2/3 innings.
“I thought it was good,” Weaver said. “I was getting a little more movement on the fastball than usual, so the ball was kind of leaking out over the plate a little bit. Gave up a few hits on just fastballs that weren’t commanded very well but just rebounded well. Got some groundballs, some double plays and that was big and just tried to manage it the best I could.”
Weaver drove in the Cardinals’ first run with a broken-bat groundout and scored a run.
Juan Nicasio made his St. Louis debut and got four outs for his third save. The Cardinals got him from Philadelphia for a minor leaguer earlier in the week.
Nicasio pitched most of the season with Pittsburgh before being plucked off waivers by the Phillies in late August. He spent just six days with the Phillies, appearing in two games.
“I’m really happy to be part of this organization,” Nicasio said through a translator. “Even more to be part of this postseason run.”
Trevor Williams (6-8) allowed four runs in 4 2/3 innings.
The Cardinals returned home in the early-morning hours after going 7-3 on a road trip that finished in San Diego. The Pirates began a nine-game swing after going 4-3 at home to start September.
Williams gave up runs in the third and fourth, and a two-run single in the fifth to Jose Martinez.
“The pitch to Martinez is the one that hurt,” Pittsburgh manager Clint Hurdle said. “Two strikes, elevated fastball. (Williams) wasn’t able to make pitches later on in some situations he got himself into. The fifth inning hurt.”
Pinch-hitter Adam Frazier singled in the seventh for Pittsburgh’s run.
TAKING A BREAK
