Selected 2011 stats
CariocaCardinal (13): Trevor Rosenthal is a player in the Cardinal organization that divides Cardinals prospect followers. Some think he is a potential #2 starter while others see his future as a back end starter or even a bullpen pitcher. Much of that difference depends on whether you just look at Rosenthal's stats or whether you consider his pitching arsenal and pure stuff, which have been described by some as top end.
Rosenthal's 2011 was marked by his usually solid K rate and K:BB rate. It was scarred by a much higher home run rate than he had the first two years of his professional career. Looking a little further behind the numbers, though, shows that he gave up home runs at more than twice the rate in the second half of the season than the first half. Given that Rosenthal pitched nearly four times as many innings this year as he had any year in the past, it may very well just been a case of him becoming worn down.
Rosenthal seems destined to start 2012 at High-A Palm Beach, but I think if he starts fast there, he could easily be moved to Double-A Springfield before mid-season. I don't see it being out of the question that he could see Memphis in 2012.
Message board community (9): Rosenthal was the community's ninth pick, receiving votes as high as sixth, with some very vocal support for being ranked high. The big pluses for Mr. Rosenthal are his velocity, youth, stamina, and makeup. One of the community reported that he hit 99 mph in a playoff game and remained at 96 mph in the ninth. Rosenthal fanned 133 in just 120.1 Quad Cities innings last year. He keeps the ball down reasonably well, with a 1.47 GB/FB ratio.
Rosenthal is working on his curveball and change, and the development of those pitches seems key to defining his ceiling. In one game late in the year, he was only using the fastball about 70% of the time, per one of our community, a sign that he is, indeed, developing his offspeed stuff. Rosenthal won't turn 22 until around Memorial Day, so has youth on his side.
At his best, Rosenthal was dominating last year. In one game, he gave up a ground ball single, then was perfect the next 8.2 innings. He threw a complete game shutout in the playoffs, and seemed generally to thrive in big game settings. Rosenthal seems to have a very strong upside as a pitcher, and I'm excited to see how his secondary pitches develop. - Gagliano
Brian Walton (14): Rosenthal holds the distinction of being the player making the most impressive leap onto this top 40 of anyone that was in the system one year ago (from ‘not ranked' to number 12 overall).
Though Rosenthal was coming off a solid, but limited in duration stint in Johnson City in 2010, others clearly saw what was coming this season. We were given perhaps our first public indication of the organization's interest in Rosenthal when he was included among a select group of players invited to early spring camp (a program that I hear will be expanded in 2012).
Named the top post-season pitcher in the Midwest League was clearly an honor for Rosenthal and a great way to top off his 2011 season. While a number 14 ranking is pretty good, I am looking to see even more from Rosenthal ahead. Specifically, I want to see him consistently dominate without having to rely so much on his fastball. That will hopefully come with more experience.
In 2012, there seems no reason he should not continue to improve in both the mental and physical aspects of his game in the Florida State League in 2012. Palm Beach pitching coach Dennis Martinez awaits, along with Rosenthal's 2011 skipper, Johnny Rodriguez.
