Answer based on context:

Toronto Blue Jays (1993–2000) All of the changes brought a competitive team to Hagerstown for the 1993 season. The offense got steady power production from Mike Coolbaugh, who led the team with 16 home runs. The best all-around hitter on the team proved to be D.J. Boston. Boston hit .315 with 13 home runs and 93 runs batted in (RBI). Those numbers were good enough to earn him league Most Valuable Player (MVP) honors. Two outfielders, Rickey Cradle and José Herrera (1990s outfielder), put together solid seasons at the plate for the Suns. Herrera hit .317 in 95 games, while Cradle belted 13 home runs. Brad Cornett led the team in earned run average (ERA), with a 2.40 mark, and also innings pitched, with 172.1. Silva went 12–4 with a 2.52 ERA in 142.2 innings. In that time frame, Silva struck out 161 batters. Overall, the Suns had a winning season in 1993.

How many strikeouts per innings pitched did Silva have?
1.13
