White Sox pitcher Jose Quintana has flashed slightly higher velocity with his fastball in his first two starts of the season. 

After averaging about 91 mph last season, Quintana is throwing closer to 92 mph this year. That may not seem like a large boost, but it's actually pretty significant. Velocity tends to improve a tiny bit as the season progresses, so things could get a little better for Quintana as he pitches more. 

The increased velocity doesn't necessarily mean he'll experience more success, but it's something to keep in mind when evaluating his performance. Quintana had a nice run last season, but was ultimately done in by his lack of strikeouts. If more velocity leads to higher strikeout rates, Quintana could be in for a surprise season. Fantasy owners would be wise to keep an eye on both moving forward.
