The regular season kicks off, but the Mariners have already suffered multiple casualties.
B.J. Upton, Tampa Bay Rays, (Lower Back Soreness)
Upton was still feeling the effects from his collision with Desmond Jennings in the outfield two weeks ago; Tampa Bay elected to place Upton on the disabled list to allow him to fully recover. The injury is being listed as lower back soreness, but the root cause of the soreness could be related to muscle strains, ligament sprains, or even bone bruising in his spine.
Strains and sprains can last for more than a few weeks but usually heal just fine. When there is a collision between two diving fielders and soreness lingers, concern about a bone bruise in the spine rises. In severe cases, this trauma can cause small fractures, but usually the player is in a lot more pain than Upton appeared to be in. While the Rays do not believe Upton’s injury will necessitate a long recovery period, they’re refusing to nail down a timetable.
A.J. Burnett finds out just what it means to be a pirate, a couple players go under the knife, and various other injuries around spring training.
A.J. Burnett, PIT (Eye)
Bunting practice is usually not dangerous; occasionally a batter might injure a finger but, only rarely does something more serious happen. On Wednesday, Burnett fell into this latter category. In the video of the incident in question, the ball deflects off of Burnett’s bat and strikes him at the corner of his eye and the eye socket. He is helped by assistant athletic trainer Ben Potenziano and walks off the field with a towel to his face. After flying back to Pittsburgh for more tests, Burnett was diagnosed with an orbital bone fracture and will undergo surgery on Friday. Bones heal at a fairly predictable pace; players usually return between four and eight weeks. Burnett will have to take it easy, but assuming there is no serious trauma to the eye itself, he should be able to start getting into baseball shape before that magic number is reached. Still, Burnett will almost certainly start the season on the disabled list.
Ryan Howard, PHI (Achilles surgery)
After Howard saw Dr. Myerson, additional information came to light. He had a small procedure to clean out stitch and surrounding tissue; the stitch was an internal one but the integrity of the Achilles repair is not compromised. This is the key: if the repair was significantly compromised, Howard may not have been able to make it back this year. Fortunately, this was not the case. During the procedure, Dr. Myerson consulted with infectious disease specialists, which revealed that Howard had an infection and the first baseman was placed on antibiotics. With news that the tendon is not compromised, the biggest issue is keeping the wound clean and not infected. Recovery from Achilles surgeries are so long and have so many ups and downs that there is no true timetable on Howard’s, but this could be seen as a relatively minor blip in the process.
Which outfielders and DHs proved to be the biggest black holes in the majors?
Picking up where I left off on Friday, we continue hunting the fish at the bottom of the major-league barrel in search of the positions where teams got the worst production—worse than the Replacement-Level Killers, but without the burden of toiling for a contending team. As with their catching and infield brethren, the following players helped produce tornado-level disasters amid their lineups, often at salaries that represented far more than just soft breezes running through their teams’ bank accounts. These are the Vortices of Suck.
There has been a major shift in the team-wide defensive rankings this season from last, but what does this mean?
Although early sabermetrics treated defense somewhat dismissively, better metrics for estimating defensive performance have emerged over the last few years. One of the oldest metrics is Defensive Efficiency (DE), created by Bill James, and this was improved by James Click in 2003 when he created Park-Adjusted Defensive Efficiency (PADE). This metric does a good job at evaluating team defense, and other metrics such as BP's FRAA, John Dewan's Plus/Minus system with Fielding Runs Saved (FRS), and Mitchel Lichtman's Ultimate Zone Rating (UZR) became available to evaluate individual player defense. However, I've begun to look at DE and PADE, and I discovered a rather peculiar observation.
