The move brought lots of hope to D-backs fans as many saw it as a response to the Dodgers’ acquisition of Hanley Ramirez. And while Johnson is an upgrade over Ryan Roberts, who was traded to the Rays earlier in the week, it’s probably wise not to get too excited about Johnson.

Johnson has been a journeyman for pretty much all of his career. He was not a highly-touted prospect and has never had a great year. In fact, he was worse than a replacement player last year according to fangraphs.com, where he had a -0.8 fWAR.

He was better in 2010, when he accumulated a 1.5 fWAR in only 94 games, and has been better this season as he has a 0.9 fWAR so far. But for comparison, Roberts has a 0.6 fWAR this season and had a 3.6 fWAR last season. So, Johnson has never had a year like Roberts did last year and is only slightly better so far this season.

I, frankly, expected a better haul for Bobby Borchering and Marc Krauss, who were sent to the Astros in the deal. However, Borchering has never been able to show he can field at any position and Krauss has been stalled in the organization for the last couple of years.

The simple truth is, the D-backs probably just didn’t regard either very highly and were willing to deal them for even a marginal upgrade. Still, if Johnson is able to finally bring some consistency to third base, it will count for something.

If he is able to account for even one Win Above Replacement for the rest of the year, that can mean the difference between a playoff spot and a spot on the couch for the D-backs.

Just temper the expectations a tad.

The 27-year-old was hitting .279 with eight home runs and 41 RBIs through 92 games with Houston this season. With Johnson, the team has control of Johnson through 2017, with Johnson not eligible for arbitration till the 2014 season.

The move came just five days after the team traded former third baseman Ryan Roberts to Tampa Bay. Third base has been an area of weakness for the team all season, as Arizona third baseman have combined to hit .230 with an on-base percentage of .285. Arizona coach Kirk Gibson has been forced to use a combination of Willie Bloomquist and recent call up Ryan Wheeler to start at third since the Roberts trade.

By bringing in Johnson, the team got a younger player with power, who hits for average, and handles the third base position well. He will hopefully stabalize the third base position for years to come.

Johnson will be joining up with the team in Los Angeles on Monday as the team opens up a three game series with the division leading Dodgers.

Are you ready for some hard-hitting analysis? You sure? Okay, here goes: David Holmberg is a stud.

I was able to finally get to a live ball game on Sunday, May 20, (living in rural Montana doesn’t lend itself to seeing a ton of ball games), so I was really excited to learn that I would be able to see Holmberg in action against a good Bakersfield Blaze lineup featuring Billy Hamilton.

In a system that is loaded with pitching talent, guys like Holmberg can go unnoticed at times. But he has legitimate upside to be a top-of-the-rotation starter.

Holmberg is a lefty with a low 90s fastball that cuts in to righthand hitters. He pairs that fastball with an outstanding change-up that made more than a few Blaze hitters look like they shouldn’t even be in single-A ball.

He seemed to also throw a slider/slurve but it lacked form and didn’t break sharply. He probably needs to develop that third pitch into an at least average major league pitch to be completely effecting at the major league level. But the two pitches he does have are plus pitches and will give hitters on both sides of the plate fits with the cutting action of the fastball and the plus change-up.

Holmberg went seven innings, striking out nine, while only giving up one hit and no walks. Holmberg, along with fellow pitching prospect Andrew Chafin, form a dynamic duo in Visalia’s rotation.

Holmberg wasn’t the only guy to watch on Visalia as short stop prospect Chris Owings is in his second year at Visalia.

Owings has always had the potential for legitimate power out of a middle infield spot and shows flashes of defensively excellence. But his approach at the plate has always been awful. I mean AWFUL. In a little over 1,100 plate appearances, Owings has struck out 258 times and only walked 37.

That includes striking out 130 times and walking 15 times in Visalia last year. He has not improved much this year, in fact, he may have regressed. He has struck out 53 times in 200 plate appearances this year.

While I was watching, I counted at least 5 times that Owings swung at a pitch WAY outside of the strike zone. One of which came on a 3-0 count where he swung at a pitch at his chest and grounded out to the short stop.

If he doesn’t improve shortly, it will be about time to give up on him.

On the bright side, another prospect that needs to prove something soon, Bobby Borchering, hit two home runs. Borchering is also repeating the single-A level as a 21-year old so a lot is riding on this season. Borchering also strikes out a ton, to the tune of 162 in almost 600 plate appearances in 2011. He has continued to strike out too much this year, especially in a league he is repeating.

He does choke up on the bat in two-strike counts, maybe trying to help his strike out total, and thats not a good sign for a slugger with his type of power.

Still, he did put a really good swing on a couple of offerings and blasted them over the right field wall, one of which came on an 0-2 pitch.

Both Borchering and Owings, absolutely have to do better than striking out once every few at bats at the single-A level.
