St. Louis Form & Recent Results

The Cardinals are heading into Saturday night's matchup desperately looking for a spark after stumbling through a really rough patch of baseball. They are currently mired in a painful three-game losing streak and have dropped four of their last five games leading up to Friday's action. The bulk of that damage happened on the West Coast, where they suffered a frustrating series sweep at the hands of the Giants in San Francisco, followed by another tough road loss to the Rockies in Denver. Even when their offense showed some signs of life, like during Wednesday’s narrow 7-6 defeat against the Giants, they just couldn't quite get over the hump. In that specific game, catcher Leo Bernal did his best to carry the load, going 1-for-4 with a big three-RBI home run, which actually accounted for the team's only deep ball of the entire night. On the mound, the Cardinals' pitching staff put together a mixed performance, racking up nine strikeouts and pounding the strike zone with ninety-eight strikes while issuing just a single walk, but it ultimately wasn't enough to rescue them from the loss column.

So far for St. Louis this season, the heavy lifting on offense has primarily come down to a couple of key bats. Right fielder Jordan Walker has been the main source of raw power for this lineup, leading the team with an impressive twenty-eight home runs. Right behind him is first baseman Alec Burleson, who has provided plenty of pop himself by launching twenty-two home runs so far this year. Burleson has truly been the engine of this offense, not only trailing Walker in homers but also leading the roster with a spectacular one hundred four RBI and a team-high .283 batting average. However, if the Cardinals want to stop the bleeding and put this slide behind them, they are going to need a much better performance from their pitching and defense. In their last five games, St. Louis has surrendered a glaring average of 6.4 runs per game, a number they will desperately need to lower as they take the field against the White Sox for the second game of this series on Saturday night.

Chicago Form & Recent Results

Chicago comes into this matchup trying to shake off a rough stretch, as the White Sox have lost three games in a row and four of their last five heading into Friday. Their recent slide looks a lot like what the Cardinals have been dealing with, and for Chicago, most of the damage came during a three-game sweep at home against the Pirates. The White Sox also dropped a home game to the Twins during that span, adding to their frustration. In Thursday’s 2-0 loss to Pittsburgh, there was not much offense to speak of, but shortstop Colson Montgomery did provide one of the few bright spots by going 1-for-3 with a double. On the mound, Chicago’s pitching staff was around the zone for most of the game, throwing 84 strikes and issuing just one walk, but the offense could not do enough to support them.

This season, Montgomery has been one of the biggest bats in Chicago’s lineup, and he is tied with first baseman Munetaka Murakami for the team lead in home runs with 31 apiece. Third baseman Miguel Vargas is not far behind, sitting at 30 home runs on the year, giving the White Sox a few legitimate power threats in the middle of the order. Montgomery has also been the club’s top run producer, leading Chicago with 83 RBI so far this season. Meanwhile, second baseman Chase Meidroth has been the team’s most consistent hitter in terms of average, leading the White Sox with a .267 batting average. Chicago has allowed an average of 4.4 runs per game throughout their last five overall, and they will be hoping to tighten things up while also getting the bats going as they try to snap out of their slump and pick up a much-needed win over the Cardinals at Busch Stadium.

Key Stats

• Chicago’s Chase Meidroth this season: 12 HRs, 51 RBI, .267 AVG
• St. Louis’ Alec Burleson this season: 22 HRs, 104 RBI, .283 AVG
