No name in the Los Angeles Angels camp this Spring Training has brought such excitement and wonder as Greg Mahle. Between mixing arm slots with some fine tuned stuff, and a bulldog mentality on the mound, Mahle has been a quick riser through the Angels farm system and is now knocking down the door of the Major League club. Whether he makes it to the Opening Day roster is for time to tell, but one thing is for sure, his rise to the top is no fluke and it's only getting quicker.


Mahle has something in his report that hardly any other pitcher possesses. Mahle splits a pair of arm slots to stay deceptive om the mound, and it's only a plus that he's a southpaw, making him more deceptive. The first arm slot comes from a near overhead slot that can drop into a 3/4 slot at times. His other falls in a sidearm to submarine delivery, where the ball comes from under his hip at batters, adding extreme deception.

As for an arsenal, Mahle mixes five separate pitches with two fastballs and three off-speed offerings. His standard fastball has natural running movement to it, sitting 86-93 miles per hour depending on the arm slot. He's able to mix speeds alone with his fastball, and uses the lower register as a sinker from the lower arm slot. He commands both fastballs well, and when his sinker is on, it has near splitter-notions to it, which can be confused for his changeup.

Mahle uses his changeup as another speed mixer, running it in around 5-10 miles per hour than his slower fastballs. It has some split notion to it as well, dying as it gets to the plate with arm-side run. Mahle also holds a slider and curveball in his arsenal, with the slider being the better of the pair. They both come in as average pitches at best, with his curve rarely being seen. His slider should develop into something more than just an average out pitch.

The biggest issue between the separate arm slots is Mahle's ability to throw pitches from every slot. He can hurl all his weapons from the high slot, but only works with his fastball and slider from the low arm slot. Hitters at the top level will pick up on this and have knowledge of what may be coming in from the low angle based on their scouting report on Mahle. If he can utilize his changeup from the low angle, things will become much easier for Mahle at the highest level.

In a strong case for being a closer in the future, Mahle has a hatred for the batter he faces. It's something necessary for a role in late relief work, and with his attacking pattern, success is evident. Though his profile doesn't fit the part of a closer, he's taken to the side of one of the all-time closers in the game's history, and current Angels' ninth-inning man, Huston Street, who never fit the part as well but found success. As Mahle takes ideas and routines from Street, he'll only excel to a higher level.

Scouting Report from Taylor Blake Ward - Senior Publisher for


As a three-letter winner in high school, Mahle put nearly as strong performances at the plate as he did on the mound. Mahle saw batting averages climb from his sophomore to senior year from .350, to .410, to a spiking .467 with three home runs as a senior. On the mound, Mahle held an 18-7 record, posting a 1.60 ERA as a junior and finishing second in the country in strikeouts as a senior.

Mahle left for UC-Santa Barbara following his prep career, and saw his bat be used less and less while he gained more time on the mound. At UCSB, Mahle hit .316/.375/.352 in 293 plate appearances, collecting eight doubles and 43 RBI. His freshman year was his best at the plate when he picked up six doubles, walking 21 times while striking out just 14, and holding a .347/.409/.379 slash.

On the mound at UCSB, Mahle held a 3.55 ERA and 1.325 WHIP in 177.1 innings of work. Mahle mixed time as a partial starter and late-inning reliever, picking up a 16-14 record, with seven saves and one complete game. In his junior year, Mahle posted a 2.70 ERA and 1.257 WHIP.

Mahle took professional ball by storm, holding a 2.65 ERA and 1.071 WHIP between two affiliates and 37.1 innings. Mahle struck out 11.8 per nine, while holding bats to six hits per nine, .187 against average and .542 opposing OPS. Mahle was primarily dominant against left-handed hitters, keeping them to a .512 OPS.

This past season, Mahle continued progressing quickly through the system, posting a 3.26 ERA and 1.276 WHIP between High-A and Double-A. Mahle picked up 25 saves over the season, leading the system with 25 - the most since 2010. Putting aside his final two appearances where he allowed two runs in two innings, Mahle held a 2.70 ERA and 1.230 WHIP in Double-A.

Mahle is giving the Angels Front Office and coaching staff something to think about this Spring Training. He's showing that he can hang with the big boys and maybe be the southpaw they're looking for out of the bullpen. However, with spots in the bullpen being up for grabs and fought hard for, Mahle falls in the category of guys who aren't even on the 40-man roster. With the lack of Major League experience and spots filling at the top, Mahle may be destined for a trip to Triple-A before emerging at the top.

The future is unsaid for Mahle at this point. He should be up this season at some point for more than just a cup of coffee with the big club, likely as a lefty specialist. However, with everything he comes equipped with, Mahle could figure in to be a fantastic setup or seventh inning man for the Angels. As stated in the scouting report, he doesn't have the look of a closer, but that doesn't mean anything in baseball nowadays if he can prove he can finish games with ease. Regardless, the Angels have an important relief arm in the lurks of their system.
