Boston Red Sox ace Chris Sale has been put on the 10-day injured list with left elbow inflammation.
MLB World Series champions the Red Sox announced Sale's move to the IL on Saturday.
Ryan Brasier has been recalled, filling Sale's spot on the 25-man roster for the Red Sox.
Sale - a seven-time All-Star - has put up some very good numbers this season, striking out 218 batters in 147.3 innings of work with a 1.09 WHIP and a 13.3 K/9 average.
But the 30-year-old has seen a noticeable dip in velocity this year in comparison to his previous two seasons.
After averaging nearly 95 mph on his fastball each of the last two seasons, Sale's fastball has averaged 93.2 mph this season.
That has led to a decrease in use of his heater as he is now throwing his slider a career-high 38.4 per cent of the time while using his fastball a career-low 46.4 per cent.
With the addition of home runs flying out of ballparks at an astronomical rate this season, Sale has a career-worst 4.40 ERA and one of his worst-ever FIPs at 3.40.
His 24 home runs allowed is three short of the career-high 27 he allowed in 2016 and he did that in 226.6 innings pitched.
Much of this could have to do with the injuries he has been dealing with since last season. He was placed on the 10-day IL with a shoulder issue at the end of last year and was limited to 158 innings which was the least he has worked since his second year in MLB as a 22-year-old in 2011.
