What It Means:

Crasnick also notes that multiple teams have already inquired, per his sources. Santiago owns a 4.32 ERA -- which is a career-worst -- in 110 1/3 innings (20 starts) this season, but the 28 year-old southpaw posted a solid 3.55 ERA across 532 2/3 innings from 2011 through 2015. Santiago will be arbitration eligible for the third -- and last -- time in 2017.

Despite the solid ERA from 2011-2015, Santiago only posted an xFIP of below 4.40 once during that time period (and it was in 5 1/3 innings pitched), and his 5.04 xFIP this season is also a career-worst. Our models project him to record a 4.03 ERA and an 18.90 strikeout percentage (league average is 21.00) over the rest of the season.
