Six Pack of Stats: Athletics 5, White Sox 4

A back-and-forth game ends with Oakland as the victor

The Athletics kept their win expectancy above 75% after Matt Olson’s seventh-inning home run, but a high leverage bottom of the ninth kept the game tight until the final out.

The Athletics avoided a series sweep against the White Sox with a 5-4 win in the fourth game of a Guaranteed Rate Field series. The Athletics (69-53) hold a half-game lead in the second AL Wild Card spot, while the White Sox (71-51) are 11.5 games ahead in the AL Central.

The Starters

Cole Irvin made his 24th start of the season for the Athletics. Irvin threw 87 pitches in a six-inning start, giving up three earned runs on seven hits and four walks while recording one strikeout. Irvin had a 4.50 ERA, a 7.01 FIP, and a 7.50 xFIP on the game.

Irvin used five different pitches in his 87 pitch outing. He generated the highest whiff rate and CSW% on his sinker, using the pitch 19 times today. Irvin lost both velocity and spin on four of his five pitches. His curveball was the only pitch that saw an improvement in velocity and his slider was the only pitch that saw an improvement in spin rate. Irvin’s curveball was his only pitch to lose vertical break, while his changeup was the only pitch that gained horizontal break. Irvin’s CSW% of 18 was 8.3% lower than his season CSW rate of 26.3%.

Baseball Savant

Dylan Cease made his 25th start of the season for the White Sox. Cease threw 102 pitches in a six-inning performance, giving up three earned runs on four hits and four walks while striking out five. Cease had a 4.50 ERA, a 7.84 FIP, and a 6.17 xFIP on the game.

Cease used four different pitches in today’s start. Like Irvin, Cease saw the highest whiff rate and highest CSW% from his second-most used pitch. He generated seven whiffs and eight called strikes with his slider. Cease lost velocity on three of his four pitches while neither gaining nor losing velocity on his knuckle curve. His 4-seamer saw a six rpm increase in spin rate, but his other three pitches saw a loss in spin. Cease lost both vertical and horizontal break on his slider and knuckle curve. He saw the same break on his 4-seamer, while gaining vertical and horizontal break on the one changeup he threw. Cease’s 28% CSW rate was 3.1% lower than his season CSW rate of 31.3%.
