Latos, 28, is a three-time 14-game winner who has been limited to just 40 combined appearances over the past two seasons because of knee injuries.
In 2015, he appeared in 24 games (21 starts) with the Miami Marlins, Los Angeles Dodgers and Los Angeles Angels, going 4-10 with a 4.95 ERA.
The Sox will hope Latos regains the form he showed from 2010 to 2013. He made at least 31 starts and pitched at least 180 innings in each of those four seasons, going 51-35 with a 3.27 ERA during that time frame.
For his career, Latos is 64-55 with a 3.51 ERA in 177 games, 174 of them starts.
I asked White Sox GM Rick Hahn about starting pitching depth at SoxFest. The projected five include ace Chris Sale, Jose Quintana, Carlos Rodon, Erik Johnson and John Danks. I noted that Johnson still doesn't have many big league innings under his belt, and 30 starts and 200 innings also will be a new experience for Rodon -- despite all the promise he has shown.
So, I wanted to know from Hahn who else the Sox had to fill in when one of the younger guys needs to skip a start, or if there's a doubleheader, or if there's an injury. Hahn cited Jacob Turner and Chris Beck as guys who would be positioned to get the nod as sixth or seventh starters.
Frankly, I didn't like that answer. Apparently, Hahn also saw that as a weakness, so he's taking what I think is a low-risk gamble on Latos. The health is a big question mark, but it's worth noting that Latos has had knee problems -- not arm problems -- and he could be the No. 3 or No. 4 starter on the Sox roster if he returns to form.
If he still isn't healthy, or struggles for other reasons, it's only a one-year deal at a bargain rate. It's not something that's going to financially hinder the Sox from making other moves.
Also, this could be a precursor to another move, because the Sox now have six starting pitchers on the roster. But I think they would want Latos to prove he's healthy before trading away any of their other guys.
At minimum, this gives the Sox more options, and when it comes to pitching, more options is a good thing.
