Spencer Arrighetti shut out the Cubs for five innings in a victory Friday.
Arrighetti walked four and hit two batters, but that only shortened his day. He struck out five and allowed just two hits. Technically, he allowed two hard-hit balls, but they were 95.7 and 95.3 mph. None of the other 10 balls in play checked in at over 89 mph. Arrighetti’s ERA is down to 1.32, even though he has a 40/25 K/BB in 41 innings. He’s allowed only one homer, even though he’s sporting a 35 percent groundball rate. This run of great luck should come to an end at some point, but it probably won’t be next week in a very favorable road matchup against the Rangers.
