Scouting Scratch: Jamie Callahan and Tzu-Wei Lin
A quick note before we get started: With Lowell starting off
their season last week, the Scouting Scratch will typically run every Wednesday
for the rest of the summer.
This year’s Lowell roster has plenty of interesting
prospects, especially in the starting rotation. This week I take a look at two
of the younger players on this year’s team, and I’ll be keeping my eye on both
of them as the season progresses.
- Selected in the second round of the 2012 Draft, Jamie Callahan (pictured) was the youngest player taken by the Red Sox last year and got a few
innings in the GCL at the end of the season. My first look at him came during
the Fall Instructional League, where I saw him throw a couple of innings
against the Rays Instructional Team. When I saw him in Lowell recently, it was
the first time I had seen him throw an extended outing.
It was immediately clear that his raw stuff had taken a step
forward since last year. During Instructs, Callahan sat 90-92 mph, but in his
first inning with Lowell, Callahan was throwing much harder, at 92-93 mph, and
touching 94 and 95 once each. He recorded one strikeout that inning on a good
92-mph fastball away from a right-handed hitter. In the second inning, Callahan
held his velocity, sitting 92-93 again, but as his pitch count increased, he
lost a bit of life and by the third inning he was more 90-91. Over his final
three innings, he topped out at 92 twice and 93 once. This was only his first
start in game action, thus the velocity drop isn’t something to worry about at
this point, but with his mechanics, it is something worth tracking as I see him
more this season.
As referenced, Callahan’s mechanics still could use some
cleaning up. He throws from almost directly over the top, and the ball comes
out almost like it would from a pitching machine. As a result, he still has
some trouble keeping the ball down in the zone. Over the course of the outing
he only got two groundball outs, compared to seven fly outs and two pop outs.
Callahan’s fastball is straight and, when elevated, very hittable; he needs to
do a better job finishing his delivery and keeping the ball down, where it did
show some movement on occasion.
Callahan also mixed in a curveball and changeup, though both
were inconsistent. He threw each pitch only a handful of times, as he didn’t
really need them since he was getting outs with his fastball. With his arm
slot, his curveball is a true 12-6, over-the-top offering. It tended to roll to
the plate in this outing, but it was noticeably harder than during Fall Instructs,
coming in 77-80 mph compared to 74-76 mph in the fall. He had some trouble
controlling the pitch, consistently missing in with it to left-handed batters.
Callahan threw his changeup in the mid-to-low 80’s, but the
pitch was firm and his arm speed tended to slow. He was more effective with it
than with his curve, controlling it better and getting a swinging strikeout.
Both pitches are works in progress, and I’ll look to get a better feel for them
when I see him next time.
- Shortstop Tzu-Wei Lin (pictured) doesn’t have ideal size for the
position, but he is athletic and has a strong overall tool set. At this stage
in his development, Lin’s standout tools display in the field with his arm and
glove. Lin showed a great feel for the position, making play after play look
easy. Lin gets himself in a good fielding position pre-pitch, and once the ball
is hit to him he displays soft hands and smooth actions. He showed a quick
glove-to-hand transfer and a plus arm. His most impressive play came on a slow
one-hopper just over the pitcher’s head, which he bare-handed and made a
strong, accurate throw, while falling over, to get the batter.
At the plate, Lin isn’t as advanced, but there is potential
in his hit tool. Lin lacks strength right now and as a result he’ll struggle
with high velocity, but in recent game action he showed a knack for putting the
bat on the ball. He sets up with his feet level and his hands low, before
bringing them up during his load. He uses a leg kick as his timing device, and is
very short and direct to the ball. He is more of a slap hitter at this point,
but he has quick hands and an advanced knowledge of the strike zone. When Lin
puts the ball in play, he puts pressure on the defense, as he is a
plus-to-better runner. On a jailbreak play when he check swung on a grounder to
short, I timed him 4.08 seconds down the line. Lin’s swing isn’t really
conducive to anything more than gap-power right now, and considering his frame,
I don’t project him to be a big power hitter in the future. Even though he is
one of the younger position players on the Lowell roster, he is one of the more
advanced hitters, especially approach-wise, and the polished college arms he
will see in the New York-Penn League will provide a good test for him.
