SATURDAY: The Yankees will also send representatives to watch Holland on Monday, according to George A. King III of the New York Post.

FRIDAY: The Red Sox are also showing some interest and will attend the showcase, which is scheduled for Monday, per WEEI.com’s Rob Bradford. Likewise, the Rangers will be on hand, MLB.com’s T.R. Sullivan tweets.

THURSDAY: The Giants are “legitimately intrigued” by former Royals closer Greg Holland and will scout his upcoming showcase, Andrew Baggarly of the Bay Area News Group tweets. Holland’s agent, Scott Boras, recently said Holland was throwing in the low 90s and would hold a showcase within the next week.

Holland missed the 2016 season after undergoing Tommy John surgery near the end of the 2015 season. He understandably struggled somewhat that year while pitching through a UCL tear, posting a 3.83 ERA with 9.9 K/9 and a too-high 5.2 BB/9 while throwing his fastball an average of about two MPH slower than the mid-90s heater he’d thrown previously. Before that, though, he was dominant, posting a combined 1.86 ERA, 12.6 K/9 and 3.2 BB/9 from 2011 through 2014.

If Holland is now mostly or fully healthy, it’s for the first time in awhile. But it’s easy to see why the Giants (and, surely, many other teams) would have significant interest. He has an extremely impressive track record, and he’ll be far enough removed from surgery by next March that it’s easy to imagine he could reemerge as an effective, or even terrific, reliever if everything goes well. The Royals have also been connected to Holland, and it seems likely other teams besides San Francisco and Kansas City will enter the fray too.
