NL West Notes: Tomas, O’Brien, Kennedy, Ottavino

Despite the high-profile signing of Yasmany Tomas this winter, the D-Backs will use him primarily off the bench in his first taste of Major League action, GM Dave Stewart told reporters, including Nick Piecoro of the Arizona Republic. Tomas was promoted today, due in part to a lack of other options on the 40-man roster, Piecoro writes. Arizona had few other position players both healthy and on the 40-man, but despite that fact, Stewart said he didn’t consider transferring injured pitchers Matt Stites or Patrick Corbin to the 60-day disabled list. Stewart feels that each is close enough to being healthy that he didn’t want to risk a move to the 60-day DL. The GM also noted that he has not considered making a trade to alleviate some of his logjam of outfielders.

More on the D-Backs and their division…

• D-Backs prospect Peter O’Brien will go about a month without playing behind the plate, manager Chip Hale tells MLB.com’s Steve Gilbert. O’Brien will see some time in left field and at first base but is apparently receiving a mental break from catching after developing an issue throwing the ball back to the pitcher late in Spring Training. Clearly, that’s not the type of issue that any team wants to see from a player it has dubbed the “catcher of the future.” Common consensus among scouts and other organizations has been that O’Brien isn’t a good enough defender behind the plate to remain at the position, though he’s certainly hitting well enough to garner some attention early in the year. Through a small sample of 28 plate appearances, O’Brien’s batting .333/.357/.519 with a homer and two doubles. Many felt Arizona should have traded for catching help this offseason, but Stewart stated on multiple occasions that such a move was not the plan, partly because the club believed O’Brien could handle the position eventually.
• Padres right-hander Ian Kennedy is nearing a rehab assignment, reports MLB.com’s Corey Brock. Kennedy is slated to throw a bullpen session on Friday, and if all goes well, he’ll join a Minor League affiliate and look to throw 75 to 90 pitches in a rehab start. It’s possible that Kennedy will need a couple of rehab outings, though he’d probably prefer to return to the field sooner rather than later. As a pending free agent, Kennedy has quite a bit riding on his 2015 performance.
• Adam Ottavino has been named the new closer for the Rockies, writes Patrick Saunders of the Denver Post. Manager Walt Weiss wasted little time this season in swapping the hard-throwing 29-year-old and former closer LaTroy Hawkins, who will now pitch in a setup or middle relief role. An effective season as a closer would do wonders for Ottavino in arbitration next offseason, as he’d stand to see a sizable raise from this year’s $1.3MM salary if he can accumulate a year’s worth of saves. Ottavino’s numbers over the past two seasons indicate that he can indeed thrive in the role, as he’s pitched to a 2.97 ERA with 158 strikeouts against 48 walks in 148 2/3 innings dating back to 2013. Of course, as a closer, he’ll be more exposed to lefties, who have given him trouble in the past, but Ottavino tells Saunders that he feels more comfortable against opposite-handed batters after making some adjustments and keeping them in check during Spring Training. Fantasy players, remember that you can keep up with all closer trends and performances by following @closernews on Twitter.
