In Jacob deGrom‘s first start of the year, he went out and dominated the Phillies. Normally, this would be reason to celebrate because it’s a sign deGrom is picking up where he left off last season. Unfortunately, there were some real problems with the start. 

Most importantly, deGrom left the start with right lat tightness. This was the latest injury deGrom has had this year. During Spring Training, deGrom also a sore thigh and a stiff back. Neither of the latter two injuries prevented him from getting ready for the 2016 season or taking the mound against the Phillies. He’s been nicked up, but as of right now, there is no discussion of putting deGrom on the disabled list. 

There’s something important to note here. deGrom is suffering from a TIGHT lat, not a TORN lat like Steven Matz suffered last year. Any discussion of deGrom missing any period of time is very premature.

With that said, you are left to wonder if any one of these injuries, or a combination thereof, has helped cause deGrom’s drop in velocity. 

After a 2015 season in which deGrom averaged a 96 MPH fastball, his velocity has noticeably dipped this year. During Spring Training, deGrom was throwing his fastball between 91 – 93 MPH. Despite hopes that he could ramp it up during the regular season, deGrom’s fastball only averaged 93 MPH. So while he ramped it up a bit, we was still three MPH slower than where he was last year. 

It’s natural to question if the dip in velocity is due to deGrom getting nicked up here and there. On MLB Tonight, Pedro Martinez presented an alternative theory. He thinks deGrom is dropping his arm when he’s pitching thereby causing the decreased velocity. Therefore, if deGrom improves his mechanics, he should be able to regain his velocity. 

Even if deGrom never finds his velocity, he can still be a very effective pitcher. In 2014, deGrom’s fastball averaged somewhere between 93 – 94 MPH. That year, he was 9-6 with a 2.69 ERA in 22 starts. By the way, this was good enough for him to be named the National League Rookie of the Year. 

While deGrom’s health and velocity is something to keep an eye on, we do know that deGrom can pitch very effectively even without the 96 MPH fastball. Most likely, deGrom just needs a day or two off to get some rest. Hopefully, he gets it now because once his son is born, he’s not getting any rest or sleep.
